 Statistics and Excel. Normal distribution, bell-shaped curve or Gaussian curve. Got data? Let's get stuck into it with statistics and Excel. After this presentation, we will be able to understand the significance, properties, and applications of the Gaussian or normal distribution, otherwise known as the bell curve. In prior presentations, we've been thinking about how we can represent different data sets using both mathematical calculations like the average or mean, median, mode, quartile, and with pictorial representations like the box and whiskers and the histogram. The histogram being the primary tool we use to envision to visualize the spread or distribution of the data using descriptive terms to describe the spread or distribution of data on a histogram, such as it's skewed to the left, the data is skewed-
